20:31:17jcowanNilby: Was that the DECUS PDP-8 implementation, or something else?
21:26:53Nilbyjcowan: Good question. I really don't remember. I assume it must have been one of the PDP8 Lisps on this page http://www.softwarepreservation.net/projects/LISP/other#DECUS_LISP_ I remember it fit on some number of "big" floppies, some of which had the "AI" Eliza and "ML" guess an animal.
21:27:50NilbyIt was at least very similar to Lisp 1.5.
21:29:39lisp123are there situations where its better to force a list to be a proper list?
21:29:40NilbyIt wasn't as good as the MIT PDP-11 Lisp though.
21:33:10Bikelisp123: when you want an actual sequence.
21:33:30Bikebut usually things aren't organized in such a way that you need to force anything to be anything
21:34:05Nilbylisp123: There's a number of CL functions that get errors or are undefined for not proper lists, but otherwise it's up to the code your using.
22:13:46pjbbut since you have to test for null, you can as well test for consp. Then if not consp, you can check for a dotted list with null only on the last cdr.
